The 2018 Kilauea volcano eruptive activities provide a rare opportunity to study the dynamic process of a volcano eruption and image the detailed magma plumbing system. In this RAPID seismic deployment project, the investigators plan to deploy a temporary seismometer array around the Kilauea volcano system including the summit within the Hawaii Volcanoes National Park and lower east rift zone in the Puna District of Hawaii. The data recorded by the seismometers will help improve knowledge on how magma moves underground and its eruption process at the surface. The ongoing Kilauea volcanic activity produces a continuous threat to the residents and visitors of the Big Island of Hawaii. A better understanding of the magma pathways, the current status of the magma body, and the dynamic process associated with the volcanic activity will help USGS and local authorities to better develop future mitigation plans. The researchers will work closely with the Hawaiian Volcano Observatory and Hawaii Volcanoes National Park to conduct the experiment and disseminate the scientific findings through their education and outreach programs to their over 2 million annual visitors.The goal of this RAPID proposal is to deploy a dense array of geophones on the southern region of the Big Island of Hawaii in response to the recent Kilauea volcanic activity. The reserachers propose to deploy three separate arrays that will cover the Kilauea summit, the Lower East Rift Zone (LERZ), and the area in between these two regions. The investigators plan to deploy ~110 autonomous three component Zland geophones to record continuous seismic signals for 30 days. Combined with the existing permanent seismic network, better earthquake and tremor source locations as well as 4D subsurface structure can be determined. The experiment should provide an unprecedented dataset to study Kilauea's volcanic plumbing system and magma migration. The raw seismic waveforms collected through the experiment will be archived at the IRIS DMC and distributed to the scientific community for analysis and redistribution immediately following the conclusion of the experiment.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

2018 Kilauea火山喷发活动为研究火山喷发的动态过程提供了难得的机会，并为详细的岩浆管道系统形象。在这个快速的地震部署项目中，调查人员计划在Kilauea火山系统周围部署一个临时的地震仪阵列，包括夏威夷夏威夷州普纳地区的夏威夷火山国家公园内的峰会和下东裂谷区。地震仪记录的数据将有助于提高岩浆在地下移动及其在表面上的喷发过程的知识。正在进行的基拉韦阿火山活动对夏威夷大岛的居民和游客造成了持续的威胁。更好地了解岩浆途径，岩浆机构的当前状态以及与火山活动相关的动态过程将有助于USGS和地方当局更好地制定未来的缓解计划。 研究人员将与夏威夷火山天文台和夏威夷火山国家公园紧密合作，以进行实验，并通过其教育和外展计划传播科学发现，并向其200万年的年度游客分发。这一迅速提议的目的是在最近的霍伊尼大岛（Big Island of Hawaii）竞争中，以对霍瓦伊（Kilauea）的大岛进行一系列密集的地球群落阵列，以响应kilaiea kilauea kilauea volcanic volcanic volcanic volcanic volcanic volcanic volcanic。研究人员建议部署三个单独的阵列，以涵盖Kilauea峰会，下东裂谷区（LERZ）以及这两个地区之间的面积。 调查人员计划部署〜110个自主三个组件Zland地球器，以记录30天的连续地震信号。可以确定现有的永久地震网络，更好的地震和震颤源位置以及4D地下结构。该实验应提供一个前所未有的数据集来研究Kilauea的火山管道系统和岩浆迁移。通过实验收集的原始地震波形将在IRIS DMC上存档，并在实验结束后立即分发给科学界进行分析和重新分配。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的智力功能和更广泛影响的评估来通过评估来获得支持的。
